Synthetic FHIR generator

Generate synthetic FHIR R4 patients and payer-exchange datasets on demand against a running Apex Atlas dev server. Everything here is synthetic — no real patient is depicted.

Requires a running API. Start the dev server locally and point the field below at it: pip install -e ".[dev]" && atlas serve --port 8080. The browser calls it directly (CORS is enabled). This is a development server, not a hosted service.

Population

Patient cohort

Configure the cohort, then Generate to stream NDJSON from the dev API.

Large cohorts take longer & return a big payload.
Connect to the API to load the module list.
Pin with a seed for byte-stable cohorts.
